My email address blocked for applying student license program

I already have a GitHub Student Developer Pack account, but when I try to re-register for the JetBrains student product programme, I get an "email blocked" error. I have participated in this programme before and wanted to renew my licence. Can you help me with this?

Thank you for your request.
Please note that some educational domains are blocked due to the previous cases of license misuse. You can't get a license with such email instantly. Please note that also GitHub's and our student checks are different. Sometimes we cannot issue licenses by email or GitHub account alone. However, you can submit a request or renew your license with an option ‘Official document’.
